refactor: simplify interfaces and improve configuration handling

- Removed unused ApiApp and ServerApp interfaces from core/apps/interfaces.go to streamline the codebase.
- Updated the GetApi method in the Server struct to return a pointer to the Api type for better type handling.
- Simplified the GetGinMode function in core/utils/config.go to always return gin.ReleaseMode, removing unnecessary conditional checks for development mode.
- These changes enhance code clarity and maintainability by eliminating redundant code and improving type safety.
